New filament

Hi,
I'm a bit new to the forum but I've been printing for a while and i know the value of good filament. A friend and I are trying to survey the community and market and design a machine that can produce Pro quality filament at a low price ( the makerbot $65/Kg is expensive but its good stuff) were looking for any suggestions or any changes you would like to see with the way filament is sold (smaller or larger quantities, new colors ect.) so were open to any suggestions. Our extruder will be open sourced and we have very ambition goals for an affordable price.

Thanks for your Imput
